To alt whom it may concern:

Be it known that we, THOMAS J. MITCHELL and James A. MCCREARY, citizens of the United States, residing at Uniontown, in the county of Fayette, State of Pennsylvania, have invented a new and useful Coke- Oven Door, of which the following is a specification. A I

This invention relates to an improvement in coke oven doors. I

Tl e primary object of the invention is to provide a coke oven door for a rectangular. or bee-hive oven which willsnugly' fit the door opening of the oven and which may be adjusted to compensate for the contraction of the refractory tile of which the 'door is.

made.

A further object of the invention is to provide a door which may be readily swung into position to close the door opening in .ueoven and in which the metallic frame of the door and its connecting membersare not subjected toheat.

i Vith the foregoing and other ob ects 1n view which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts and in the details of construction hereinafter'described and claimed, it being understood that changes in precise embodiment of theiinventio-n herein disclosed can be made within the scope of what is claimed without departing from. the spirit of the invention.

In the drawings-Figure 1 is a sectional view of a portion of an oven,,showing the door and its supporting mechanism in (and elevation. Fig. 2 is a front elevation of the door. Fig.- 3 is a vertical section on the line of Fig. 2, and Fig. 4. is a section on the line 4-4 "of Fig. 2, the door in this view being shown as positioned in the door 'openin of the oven, the mud or loam being shown etween the door and oven.

Both of the sections of the doors are formed of a plurality of bricks which are disposed vertically of the frame,.the meeting edge 11 of one brick, being'formed with.

a groove .12, which receives the rib 14 .frorn'ied. integral with the edge 15 of the adjacent-brick. These bricks are of a number consistent with the width of the; door, the bricks being substantially rectangular, the upper edges of the bricks forming the upper section of the door bcing'curved to conform to the curved portion-17 of the frame 18 of the upper section. These curved upper-ends arev beveled as shown at 19, conforming I of the oven. The upper section of the 'door consists-of the upper and lower frame being composed of angle ironformed to an acute angle so as to firmly grip the inclosed brick or tile, the tile being formed receivethe frame member 17, the frame and the beveled surface 19 being co-extensive.

rangement as when the door is forced in position, as shown in Fig. '4, the heat cannot Contact with the metallic frame. The

conform to the curvature of the door open ing of the oven, embracing the outer, edges of. the tile -and 26.

An angle iron 27is secured to each of the vertically extending portions 22 and 24 of the curved bar'l't' of the frame 18, the upstanding portions 28 of said angle irons receiving a bolt 29. The lower section of the frame which consists of the angle bar 30 and the vertically extending portions 31 .have secured to each of itscorners, a plate 32, said plate being provided with elongated slots 33 through which bolts 34 pass, the plate beingvertically adjustable on the vertically extending portions 31 of the lower sections of the frame. each provided with the upstanding portion 34 which is in alinemcnt wit-h .the upstand- -ing portion 28 of the angle bars '27, the bolts 29 passing through the upstandin portion 34 of the plate 32. 'It will be noted by this construction that the. two sections which constitute the frame of the upper door section may be drawn together to comtiles are provided with ve'rticall' extendin grooves 35 to receive the vertical y dispose rods 36. These rods passthrough the lower bars pass through Washers 37 placed on the ceiye .nutsQit being noted: that when said nuts areptightened, the two frame members between} their adjustable connected plates may be drawn together. I

In the drawings, each of the sections of the door are provided with three of the rods -36, the central rod as shown in Fig. 3 of the to the bevel 20 of the door opening members 18 and 18,these frame memberswith a recess 21 which at their upper edges upper section 17 of the frame is curved t-o' curved portion of the curved upper section 17. The upper terminals of these bars rte- ,105

Particular attention is called to this 3.1.

Sii

The plates 32 are i as I,

pensate for the contraction of the tile. The

I bar 30 of the upper frameand thetwo outer lower sections, the lower section 39 having the same frame construction as the upper section,'th'e upper longitudinal beam of said lower section being straight, to conform to the lower beam 30 of the upper frame the frame of the lower section being drawn together by adjusting the bolts 29 and the verticall extending rods 36'. It will the door frame maybe clamped to the tile regardless of the degree to which the same contracts when exposed to heat for any length of time. It will also benoted that the adjustment of the frame may bereadily accomplished while the door is in position. Particular-attention is called to the pe culiar formation of the fire surfaces of thetile, it being noted that by referring to Fig. i of the drawings, that when the door is positioned within the [door opening of the oven and the loam ofmud 40is placed bethe fact, that any r the metal frame of the door and even though the tile with which the door is formed should contract, the heat will not contact be noted by this construction that 7 with the door frame even before the bolt members are tightened to clamp the frame to the tile.

i/Vhat is claimed is:

1. A coke oven door consisting of a frame, tiles of refractory material supported by said frame, said frame being adjustable to compensate for the contracting of the tiles.

'2. A cokc .oven door consisting of a frame, tiles of refractory material supported by said frame, said frame being formed in sections, and adjustable means connecting said sections.

3. A coke oven door consisting of a frame, tiles of refractory umterial supported by said frame, said frame being formed in sections, and vertically disposed adjustable members connecting said sections.

at. A coke oven door consisting of a frame, tiles of refractory materiah-a frame formed 'in sections embracing said tile, the sections of said frame being adjustable with respect to each other.

5. A coke oven door consisting of a frame formed in two sections, tiles of refractory material embraced by said frame, means for drawing the frame togcther intermediate their ends, and means for drawing the same together at their ends.

In testimon that we claim the t'orcgoin b as our own, we have hercto aflixed our signatures-in the presence of two witnesses. THOMAS J. lMiITOl-TELL.
